Separation and characterization of phenylamides fromPiper kadsurausing preparative supercritical fluid chromatography and ultra‐high‐performance supercritical fluid chromatography‐tandem mass spectrometry

Abstract: A preparative supercritical fluid chromatography method for the separation of Piper kadsura obtained five phenylamide compounds, which had the same structural skeleton, but changed in the number and position of methoxyl substituents. To improve the separation selectivity of these structural analogues, silica, phenyl, and chiral stationary phases were screened. Only through the combination of Chiral C and phenyl columns could the separation of the five phenylamides be solved. The two‐step strategy using prepara… Show more

“…Liquid chromatography–mass spectrometry (LC-MS) analysis can quickly and accurately describe the chemical components in TCM. In previous studies, various data post-processing technologies have been invented to comprehensively identify herbal components in complex sample matrices, such as MDF or EIC ( Pan et al, 2018 ; Wang et al, 2021a ; Dai et al, 2021 ). Data-independent acquisition (DIA) provides comprehensive untargeted acquisition of molecular data, while data-dependent acquisition (DDA) displays a signal detected in a given sample.…”
